A CORPORATION OF ILLINOIS :DEMOUNTABLE HINGE AND FASTNER roncovnns` onLins- Application filed November This invention relates to carryingdevices or cases for typewriting machines, but has particular relationto means for demountably hinging and fastening the covers thereof totheir bases, and it consistsin certain peculiarities of theconstruction, novel arrangement and combination of the various partsthereof las will be hereinafter more fully set forth and lspecificallyclaimed. Y

The principal" object of the invention is .to provide avery simple andinexpensive device to be used on the covers and bases on whichbasestypewriting machines may beinounted for securely holding said partstogether, but which will permit them to be readily de sitions they willoccupy when thepartsof the case are Vfastened together.

Fig. 2, is a view in elevation of the rear wall of the casing, showingit fore-shortened for the convenience of'illustration, and equipped withmy improvements. o

Figs. 3 to 5, inclusive, are detached perspective views of details ofthe invention.

Similar numerals of reference designate like parts throughout theVdifferent views of 4o i' the drawing.

Referring. now to ence numeral 6 designatesthe inverted box'- likeportion of a carrying case for" 'type- V writers which portion has itslowerfendopen in which the base ,7 of the case snugly fits. Upon thisbase 7 may be mounted in the usual or any preferred,wayatypewritingmachine (not shown) Vfor which the function of the case is tolsupportand carry such a machine,

To the rear end of the lower surface ofthe the drawings, the refer-y 9,1925. Serial No. 68,041.

base 7, is secured in spaced relation to one Y another apair of l'anglebrackets, designated as awhOle,v by the lnumeral 8, each of whichconsists of a base portion 9, and an upright part 10. The uprightportion of'each ofthe brackets is provided with a vertically disposedslot 11, each of which extends fromnear the upper surface of the base 7,to a suitable 'y pointnear the upper end of the uprightpart 10 in whichit is located. It will be Vunderstood that these angl brackets 8arepermanentlyflxed to the base 7 f of the case and in such away thatthey as well as the base can be freely inserted bef tween' the front'and rear end walls of the case.

The rear end wall 12 of the box-like part of the case ,6 is provided inits lower end 'or portion with a pair'of vertical slots 13 which4 arespaced `from each other in parallelism and so as tok'coincide with theslots 11 of said i4 is secured to the wall 12 so as yto cover the slots13 therein. Thus it will'be understood that the flange 15 of each of thebrackets 14 will rest under the lower edge of said wall. At the middleof each liiange 15, is punched out of or otherwise formed andsecuredthereto a holding member for an upright forked spring catch, designatedas a whole byk the.v

numeral r16, each of which consists of anup-` rightarm 17 having at itsupper end a forward extension 18 and its lower end provided with anopeningl 19 to receive said holding` member, which is designatedby thereference numeral 20 and whichholding member, in the present instance,consists of a projection' 21st-ruck out of and turnedupwardly and thenlongitudinally in a horizontal planev with respect to itsfiange 15,rupon the horizontal portion of which the opening 19 of the member 16 istted. Each of the flanges 15 also has, in the present instance, struckup from its middle portion a projection 22, the upper portion of whichlies at the free end o the part 21 and serves to hold the member 16 inposition.

The lower portion of the arm 17 terminates in a flat straight line as at23, see Fig. 4, and rests against that portion of each of the flanges 15from which the projection 22 is struck up. Just rearwardly of each ofthe openings 19 in the arms 17 is provided a. rounded portion 24 fromwhich is upwardly extended a spring member 25 which latter contacts atits upper end with the inner surface of one of the brackets 14 directlyrear wardly of the extensions 18 which normally project through theslots 13 and each of which said extensions is provided on its frontsurface with a downwardly and outwardly inclined part 18 as shown inFigs. 1 and 4 of the drawings for the purpose of co-acting with theupper end of each of the brackets 10 to force the Catch members 16rearwardly when the box-like part 6 of the casing is being placeddownwardly over the base. During this operation it is apparent that thespring members 25 will yield sufficiently to permit the members 16 beingdeflected outwardly7 after which they will press said members forwardlythus causing them to pass through the slots 11 so as to engage the upperends of said slots and thereby prevent the raising of the box-likemember of the casing.

From the foregoing and by reference to the drawings, it will be clearlyunderstood and readily seen, that, assuming the cover or box-like part 6to be in its fastened position as shown in Fig. 1 of the drawing, it isohvious; that by slightly tilting the front part of the coverrearwardly, the arms 16 will be caused to be released from the slots 11and the front ends of the extensions 18 to contact with the brackets 8just above the slots 11 therein. In this position of the parts, it isevident that the cover can now he removed from the base and the machinemounted thereon. The operation of fastening the cover to the base hasbeen before explained, and it is deemed unnecessary to herein repeatsaid explanation.

Havin0r thus fully described my invention, what I c aim as new anddesire to secure by Letters Patent isw 1. In a device of the classdescribed, the combination of the base of a carryinor case with a pairof spaced brackets vertically extended from one edge thereof and eachhaving a vertically disposed slot, an inverted box-like cover adapted toreceive at its lower portion said base and provided in one of its wallswith a pair of vertical slots to coincide in part with said slots in thebrackets, another pair of brackets secured to the cover over the lastnamed slots and each having a flange at its lower end provided with aholding member, and a bifurcated spring catch mounted on each of saidholding members and extended vertically in said coinciding slots.

2. In a device of the class described, the combination of a carryingcase base, a cover therefor, and disengageable means for releasahlyfastening the base and cover together, said means comprising a slottedmem ber on said base, and a spring catch member on said cover having aportion thereof locatable in the slot of said slotted member when saidCover and base are in closed relation, said catch and slotted memberbeing so associable that said catch may be rotated out of engagementwith said slotted member upon disengagement of said cover and base.

3. In a device of the class described, the combination of a carryingcase base, a cover therefor, and disengageable means for releasablyfastening the base and cover together, said means comprising a slottedmember on said base, and a bifurcated spring catch membei` comprising anengaging prong anda biasing prong, said engageable prong being locatablein the slot of said slotted member when said cover and base are inclosed relation, said catch and slotted member beingT so associated thatthe engageable prong may he rotated out of engagement with said slot tedmember upon disengagement of said cover and base.

4. In a device of the class described, the combination ot' a carryingcase base, a cover therefor, and disengageable means for releasablyfastening the base and cover together, said means comprising a slottedmember on said base, a bifurcated spring catch member comprising anengageable prong and a biasing prong, and a bracket member sccured tosaid cover and upon which said spring catch is so mounted that saidbiasing prong functions to force said engaging prong into the slot insaid slotted member when said cover and base are in closed relation,said members being so associated that said engageable rong may berotated out of engagement with said slotted member to release said coverfrom said base.

5. In a device of the class described, the combination with a carryingcase base and an inverted box-like cover adapted to receive and closesaid base, of securing means comprising a bracket secured to one edge ofsaid base and having a vertically disposed slot above said base, and aspring catch member for engaging a portion of said base bracket, saidcover being provided with an opening in which said catch is receivableso that the major portion of the operating parts of said catch arecontained within said cover opening.
